HEART RATE SPEED INTERVAL
Description
Focus on power and speed in this controlled workout that alternates one-minute intervals of 65% and 85% of
theoretical maximum heart rate (or user-specified target heart rate). This challenging workout combines steeper
(higher resistance) intervals with changing speeds. Intervals last one minute after the target heart rate has been
reached. Use Level+ / - to adjust interval target heart rates mid-workout.
WARNING!
Consult a physician before you start an exercise program. Stop exercising if you feel pain or
tightness in your chest, become short of breath, or feel faint. Contact your doctor before you use the machine
again. Use the values calculated or measured by the machine’s computer for reference purposes only. The heart
rate displayed on the console is an approximation and should be used for reference only.
